Abstract: Certain features relate to compensating for a roundtrip delay caused by a distributed antenna system. A delay unit communicatively coupled to a base station can intercept the delay compensation signaling communicated between the digital baseband unit of the base station and the radio transmitter unit of the base station. The delay unit can adjust the delay compensation signaling by adding to the delay compensation signaling the pre-determined fiber delay caused by the DAS. In some aspects, the delay unit can delay the control words for a base station operating under the Common Public Radio Interface standard. In other aspects, the delay unit can delay the round-trip time measurement message for a base station operating under the Open Base Station Architecture Initiative standard.

Abstract: A request is sent from a first base station to a second base station for a transport layer address assigned to the second base station that is suitable for establishing a connection between the first base station and the second base station. The second base station determines whether to include an outer address assigned to the second base station in a response to the request. If that is the case, the second base station sends the response to the first base station that includes a tunnel inner address assigned by a security gateway to the second base station and the outer address. The first base station determines whether the outer address is included in the response. If that is case, the outer address is used to establish the connection between the first base station and the second base station without using the security gateway.
